12 group-based extended care treatment sessions scheduled in 3, 4-week periods over a 12-month period

BEHAVIORALself-directed treatment

provision of treatment materials with instruction to work through materials at participant's own pace

Inclusion criteria

* At least 21 years-old * body mass index (BMI) = 28.0 - 45.0 kg/m2 * willing to provide informed consent and accept randomization

Exclusion criteria

* BMI \>45 kg/m2 * Illnesses requiring medical attention and/or conditions for which weight loss and moderate physical activity would be inadvisable: diabetes not under active treatment, myocardial infarction or cerebrovascular accident within the last six months; unstable angina within the past six months; congestive heart failure; cancer requiring treatment in past five years (exception: non-melanoma skin cancer); serious infectious diseases (e.g., self-reported HIV); chronic hepatitis; cirrhosis; chronic malabsorption syndrome; chronic pancreatitis; chronic lung diseases that limit physical activity; orthopedic injuries or conditions that significantly limit physical activity. * Conditions or behaviors likely to affect the conduct of the trial: unwilling or unable to give informed consent; unable to read English at the 5th grade level; unwilling to accept random assignment; unwilling or unable to travel to attend intervention (due to distance from clinic, work schedule or other scheduling conflicts); likely to relocate out of the service area in next 18 months.
